Re: P1.24 of LPC2214 doesn't work - Herbert Demmel - Oct 11 18:45:57 2006
Hi,
sorry, I obviously was already too tired to see the obvious: it should be
(1 << 24) instead of (1 << 25)
Regards
Herbert
>> I'm trying to use P1.24 of a LPC2214 as an output but the port pins

>> to pull the pin low (PINSEL2 bit 3 has the correct state, P1.20 is not
pulled low at reset). If I try to do the >> same with e.g. P1.16,
everything works as expected.
>> Any idea?
Regards
Herbert
